The tables in this section list some typical materials and thickness ranges that can be measured with ultrasonic gages, using specific transducers and appropriate instrument setups. 1. They produce an output signal in the form of some variation in resistance, capacitance or any other electrical parameter, which than has to be converted to an equivalent current or voltage signal. STUDY. • Input full scale = 110 °C. transducer accuracy is specified by the manufacturer as a percentage of full range e.g. Operating range defines the maximum temperature range for using the transducer. Explore the wide range of Philips ultrasound transducers. Characteristics of Transducers 2. %PDF-1.5 But if the physical force is converted into an electrical signal, then their value is easily measured with the help of the meter. Generally speaking, units in the 100-200 watt range are sufficient for shallow water use and units up to 1,000 watts and more may be necessary to probe deep canyons and drop-offs. This process mainly includes a sensing element to sense the i… There are many more possibilities. <>>> The tables in this section list some typical materials and thickness ranges that can be measured with ultrasonic gages, using specific transducers and appropriate instrument setup Thanks for reading about “characteristics of transducer”.
